• MP asks Karren Brady why board were silent after fan threatened• Club were alerted to abuse by supporter group before meeting them

West Ham United have been described as behaving like “ostriches with their heads in the sand” by a Labour MP who has written to Karren Brady demanding to know why the club have not condemned the abuse and threats aimed at the chairman of one of their supporter groups last week.

Wes Streeting, the MP for Ilford North, has contacted West Ham’s vice-chairman to ask why the board has remained silent after Mark Walker, the head of the West Ham United Independent Supporters Association (WHUISA), was left fearing for his safety after becoming the target of an online campaign orchestrated by a rival fan group, some of whose founders are former hooligans and which has links with an unrelated group condemned by anti-racism campaigners.
